another telephone is still not connected to the Call Server. When the far-end
telephone registers, the partially-rebuilt call is promoted to REBUILT state.
PREB
The ACF call is PARTIAL-REBUILT (PREB). This is when no
call-associated data is found. The far-end IP address is not known on the Call
Server, or the far-end IP address is translated to the virtual trunk TN or Voice
Gateway TN. The Call Server creates the data leaving the far-end TN
undefined.
This scenario happens when:
• the far-end telephone is a local telephone, but while it was registered with
the remote Call Server, the local Call Server was cold-started and
TN-to-IP address associations were lost.
• the far-end telephone is a remote telephone.
The terminating-party TN in the PREB call is 0.
Note: No signaling is passed to the far-end telephone involved in the
HREG, HREB, and PREB calls. This means any features that involve
both parties do not work with such calls.
REB
The ACF call is REBUILT (REB). This means the calls have both parties
available, but all call data except bandwidth and connected transducers is lost.

LD 32 STAT command

If ACF information exists for the requested IP Phone, it is output as follows:
ACF STATUS <status> TMR <timer>
where <status> is:
• UNREG for unregistered calls
• HREG for half-registered calls
